What did I change? I added a + 1 % population growth bonus to every region information 'building'. This way you can play on huge unit size without having the AI emptying its settlements. There are a few exceptions: Some provinces, e.g. the Orcades, already had a 0.5 % population decrease in DOB; those regions only got a + 0.5 bonus to keep the balance the same.
Installation:
Install VI 2 and DOB, then unzip the attached file into your Rome/BI/VI2/data folder. Better make a backup of your export_descr_buildings.text to be able to revert to vanilla if you don't like my changes.
